We are in a position to run that take a look at and get an immediate readout to substantiate help for QC 3.0, for instance, with no need to have suitable telephones or devices readily available.
Power supply and cables
All of our checks had been carried out utilizing the identical wall adapter and, when attainable, USB-C or Micro-USB cable. This was executed to get rid of any discrepancies with wall adapters and cable throughput.
